DigiTimes also reported on Tuesday that PCB suppliers for iPhone 12 "are set to enjoy a strong fourth quarter of 2020 with their sales growth momentum to carry on through first-quarter 2021", with companies like Zhen Ding Technology and Compeq Manufacturing "likely" to hit record levels of revenue in Q4 of 2020.
"In the past, the number of folding tests for laptop hinges was about 20,000 to 30,000, and those with better specifications were up to 50,000".
Apple has reportedly started sending foldable iPhones to its assembly partner Foxconn for testing purposes with a possible release in September 2022. However, the test for mobile phones requires more than 100,000, and the specifications are more stringent. Foxconn will take care of the assembly, the report added.
The report added that Apple was now deliberating on the use of OLED or micro-LED technology for the first foldable iPhone screen.
More specifically, DisplayMate praised the iPhone 12 Pro Max for absolute color accuracy, image contrast accuracy and intensity accuracy, full screen brightness, full screen contrast rating in ambient light, screen reflectance, brightness variation at viewing angle, and visible screen resolution.
